Building castles in the (Northwoods) airEvery winter since the late 1920s, a glittering ice castle is constructed in Eagle River, Wis., and 2012 volunteers are ready for the task. Nearly 3,000 12-inch-thick ice blocks from a local lake are hauled to downtown Eagle River, the Snowmobile Capital of the World, where the structure is erected between Christmas and New Year's Day. A new design is sculpted every year and depending on weather, the Ice Castle normally stands until late February. Located on a major snowmobile trail, hundreds stop to have pictures taken in front of the design and it's also lit at night. Dec. 25 to Feb. 28 in downtown Eagle River. (800) 359-6315 or eagleriver.org.
